I may be wrong, but for those who take the time and effort to build 
their own Unbound, I see them either using a root.hints file because 
they know what they're doing, or not because they've never heard of it 
(or because they know what they're doing)

I'm sure there's some small group that will create one and abandon it, 
but I just can't imagine that this type would remember to manually 
update the binary.

I agree that it's worth doing, but the keep-it-simple of just reading 
the configured file or not seems like it's more valuable than guessing 
at whether the file should be used or ignored. Also, the principle of 
least surprise, a user will expect that the file will be used or not.
